Answer:
30kg
Explanation:
Distance between Alok and father = 5m
Father's distance from fulcrum = 2m
Solak's weight = 20kg
Unknown:
Weight of the father = ?
Solution:
This problem entail the balancing of forces around a fulcrum.
In this problem;
workdone by father = workdone by Alok
( mass x distance) father = (mass x distance) Alok
distance of Alok from the fulcrum = 3m
Input the parameters and solve;
mass of father x 2 = 20 x 3
mass of father = 30kg
The weight of the father is 30kg

Explanation:
chemical to thermal to electromagnetic
Explanation:
The best statement that shows the energy transformations that took place is from chemical to thermal to electromagnetic energy.
- In all isolated systems, energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.
- The firewood contains a chemical potential energy at rest. This energy is contained in the carbon chains of organic compounds it houses.
- When combustion takes place, kinetic energy in form of thermal energy is liberated. The bulk is in form of heat.
- This energy dissipates in all direction as a form of radiant electromagnetic energy in the infra-red range.
